MMIC Silicon Bipolar Differential Amplifier
Features
The ISL55016 is a high performance gain block which can
match a 75Ω single-ended source to a 100Ω differential
load. This feature makes the ISL55016 ideal for a wide
range of general-purpose applications such as Satellite TV.
The ISL55016 can be used as single-ended to differential
converter and eliminates the need for an external balun
structure.

Typical Application Circuit
The ISL55016 can configured so that it is driven with a
single-ended input. If either pin 2 or pin 3 is used as a
single-ended input, the other needs to be connected to an
AC ground. The input is internally matched to 75Ω
single-ended and the output is matched to 50Ω single-ended
or 100Ω differential.

The ISL55016 Silicon Bipolar amplifier can match a 75Ω
single-ended source to a 100Ω differential load. This feature
makes the ISL55016 ideal for a wide range of general
purpose applications, such as Satellite TV.
ISL55016 is a true differential amplifier. Figure 29 shows the
Typical Application Circuit of ISL55016. Pins 2 and 3 are

Balun Function
In many applications of ISL55012, the amplifier will be
followed with a Balun structure to transfer the single-ended
signal to a differential tuner. The ISL55016 will eliminate the
need for an external balun structure and provide significant
savings in BOM cost and PCB real-estate (see Figure 30).

FIGURE 31. PCB LAYOUT OF MATCHING NETWORK
Trade-off Between Power and OIP2
Matching at the Input and Output
The values of R1 and R2 (Figure 29) have two options; 27Ω
and 0Ω. Decreasing the R1 and R2 value will increase the
voltage across the output transistor leading to an increase in
the dissipation power. At the same time, it will increase the
amplitude of the compression, OIP2 and OIP3. Figures 21, 22
and 26 show this effect on OIP2. Figure 25 shows the
compression point changed with different resistors. Figure 28
shows the OIP3 changed with different resistors. One needs
to trade-off between the power dissipation and higher OIP2.
In the PCB Layout Design, a matching network is needed,
especially at the input. Figure 31 shows the matching
network used for the ISL55016 Evaluation Board. 12mm
100Ω trace and 6mm 50Ω trace are used to form the input
matching network and 4mm 100Ω trace to form the output
matching network on the FR4 material.

In Figure 31, the S11 is improved at 2GHz with the matching
network, to less than -10dB.

Thermal Management
Evaluation Board Setup
The power dissipation of ISL55016 is about 500mW. The
recommended layout is shown in Figure 31. The ground pad
should be placed under the bottom of the device. At least
two thermal vias are needed to lower the temperature.
The Evaluation board is designed to connect directly to the
2-way 180° Power combiner to recombine signals from
-2GHz and allow single-ended assessment with good phase
matching the two differential signals into one single-ended
output. For lower frequencies, a different choice of power
combiner is needed and short matched coaxial cables
should be used to connect to the combiner. This setup is
used on noise figure measurement and differential
OIP2/OIP3 measurements.
Choices of Components
ISL55016 is designed for wide bandwidth applications, from
50MHz to 3GHz. The decoupling and RF choke components
should be chosen carefully for different frequency
applications. Tables 1 and 2 list the components used on the
evaluation board.
